Vine acum ! Ai putina rabdare !
Primul meu contact cu Tandberg - un vecin in bloc avea un mag X-Field 3300x si un receiver cu boxe, ambele Tandberg.
Aici o evolutie a magurilor Tandberg, including top of the line TD20A

Despre cass deckuri, cele mai bune au inceput cu seria 3000 - TCD 3004 avea un design f. interesant, industrial
The TCD 3004 features a microprocessor-controlled 3 head, dual capstan closed loop mechanism with 4 servo-controlled motors and Dolby B noise reduction. The individual motors (capstan motor, pair of motors for the belt-driven supply side and take-up side hubs, plus head bridge motor) are constantly monitored by the computer. This allows the deck to wind at fantastic speeds without risking tape damage as well as ensuring incredibly stable tape path with minimal wow & flutter.
Like the 3014/3014A, the 3004 mechanism is built on a 5mm thick pressure-rolled aluminum plate which ensures rigid support for the moving parts. It has very large flywheels of differing diameter and drives them with belts of completely different size, to minimize the chances of any resonance. The hubs are belt-driven by two separate motors and those belts are again asymmetrical. No detail was overlooked in making sure this deck had the smoothest and most accurate mechanism available at any price.
The record head azimuth is adjustable from the front panel using a built-in test tone, ensuring proper frequency response on every tape you record. It also offers a tape selection switch for Type I, Type II, and Type IV (metal) tape types and has front panel adjustment and test tones for setting azimuth as well as adjusting the bias and record current levels for whatever tape is loaded. The system uses a unique separate calibration meter and is really simple to use.
The level meters are true peak-reading design with slow decay and are connected to the signal path after the record equalization so they monitor the signal being applied to the record head, not coming into the record amplifier. This provides for maximum accuracy in setting optimal recording levels.
In addition, Tandberg included Dyneq and Actilinear, their two proprietary technologies to extract maximum performance from the cassette format. Dyneq works similarly to Dolby HX Pro to extend headroom during recording, with the use of dynamic record equalization. Actilinear is a transconductance amplifier that combines the music and bias signals and converts them to pure current, allowing bandwidth so wide it can actually pass square wave bias frequencies.
The build quality of these decks is also exceptional. Tandberg specified the use of expensive metal parts wherever needed to ensure stable, accurate tape handling. They also used high-grade components throughout the electronics, such as polystyrene or polypropylene capacitors. This resulted in an ultra wideband design able to pass a signal with no audible degradation in sound quality or imaging.

Seria a continuat cu totl TCD 3014 - cu diverse subvariante - sau cum se numea " the Dragon killer " - si un updated TCD 3034
Evolutia s-a terminat cu seria TCD 910 / 911 - de fapt mai mult professional edition called Master Edition - aceste deckuri au numai fct PLAY, fara REC - se foloseau pt redare la posturile de radio

Precum bine zicea momolo, aceste deckuri - f.f.f.f sensibile, se defectau f. usor, greu de recalibrat,etc. In schimb, Performante de top.
